These drawings show a'n elongated frame 1 Consisting of two sliding sections bolted tof length may be varied. *Ajnumber of rollers 3 are laterally spaced along'the top of'this by a lever 5 so as to lock v'them againstrota- ,upwardly on a p the frame 1. 'A- set of-"rolling units .8 is fixed under the frame 1 at the end carrying 3 the runway 6 rolling units may be of any character, the

illustrations showing, them in caterpillar form so that the apparatus may be used on soft. or rough ground. v

A mobile self-driven power, unit 10 is fixed on the frame 1 adjacent its runway" by clamps 11. To prevent "(the weight ofthis' 1 unit injuring the rollers 3 blocks 12 are pref'-' ,erably placed beneath it,':and

4 the runway '6 has a raised portion 13. This power unit .in-

cludes a pluralityofcable drums. l iand a power take-off1 5. This take-ofl: is connected clutches 21. Cables 22 connect these '10. Of course, these drums are all provided Figures 7and ;8 {are respectively top plan 'gether through a plate 2 whereby the .frames ti'on, A'declined runway 6, which inayswing pin-7, is fixed to one end of z and another set'9 is swiveled under the other end of this frame.

which 3 .d'rives a Epair of drurns 20 through drums 'o to swing the swiveled rolling units 9,

\ *Thefother end of the frame 1' carries a v hoisting, rig consistin'g'iof a stiff A-fra'meg strut-23 and a boom 24. This rigis fixed to I I the'fjraine by pins 25 so that it may easily be demounted; Its various operating cables 26 are fixed tothe drums' 14 of thepower unit l with clutches and brakes I i ofthe' usual type,

Thefclutches arm also be. provided with suitable connections 28" to the levers 27 so'that' the entire unitf nayi be]- operated from one point. Preferably the 1, frame 1- is provided with jack's'29 which carry thGlOfi-d while the hoisting rig is being used.

'One of the advantages of the; apparatus just described is that it obviates. the necessity of running track extensions from a railway" I siding to a job.) Assuming that the struc-', 'turalsteel is on cars at arailway sidingand that/the point where they are to be erected is some distance away, the apparatus-is drivento the railway siding'where-theboom 24 is" lowered totheground and disconnected",

from the frame 1,"after",which the stiff*A- "frame strut 23 isg'also demounted):The;

power unit. 10 is then' unclamped from the frame 1 and driven down-therunway 6' to 7 the: ground, The: hoisting rig is then set up adjacent the car in theusual manner (Fig ure- 7-)L and its cable's, which were disconf nected from the drums lt during. thede mounting operation, are reconnected thereto. Bythe use of thishoistingrig a numb'erof the structural steelsections aretrans ferred to the frame The cabl'esi26 are 9 then disconnected-from the-drums 14 0f the .power' unit10 "and this unit' is hitched tothe V swiveled rolling'units19*(Figure 8) through; a'draw-bar 30. By this means these loaded sections are transported to the point where they'are to be erectedi Rough groundwill V not interfere'withthe progress of the appa ratus because of its rugged *character, the runway 6 swinging upwardly oni the pin? r'- it strikes an obstruction,

When the point of erection is reached the lever 5 is operated to unlock the rollers 3 so that the structural sections may be run off the frame 1 and down the runwayfi to the ground without damage. The apparatus is then driven back to the pile'of structural.

steel sections and the foregoing operation repeated until all have been transported to their point of erection. The power unit is then reinstalled on the frame 1, the stifi A-frame strut 23 remounted and, with the latters aid, the boomr24s remounted. The

various cables 26 are reconnected to the drums 14 and the chain 16, which was of course removed when the power unit 10 was demounted, replaced. The apparatus isthen drivento the job and used as a mobilecrane to erect the steel sections. i w I -It will be seen fron the foregoing that the apparatus is at all times amobile self-driven unit which is extremely flexible in its opera tion and which may be adapted to a variety of uses. The power unit, the hoisting rig, and the truck produce a. coaeting combinetion of great usefulness and adaptability.

Although a specific form of this apparatus it has been shown and described in accordance with the patent statutes, itis not intended to a limit the scope of the inventionexactly thereing units under the runway end of said frame, a swiveled set of rolling units under the other end of said frame, a mobile selfdriven power unitremovably clamped on 7 said frame adjacent its runway constructed with a plurality ofjcable drums and a power take-off, means for connecting said power take-off to drivesaid fixed set ofrolling units,
